Be it known that we, GERnMm PIERBONI, a subject of the King of Italy. and PASQUALE BUFANO, a citizen'of the United States, residing at Connellsville, in the county of Fa Yette and State of Pennsylvania, have invente new and useful Improvements in Coke-Ovens, of which the following isa specification.

This invention relates to certain new and useful improvements in cokeovens.

The object lof the invention is to produce an oven of this character of maximum strength and durability to withstand the in-v tense heat as Well as the strain ofthe gas explosions which constantly occur in the manuacture' of coke. Y

`Ansther object is to provide an oven of To all whom/'tammy concern: 'l f to resist the force of internal explosions and also to counteract Whatever force which is- In carrying out our invention we provide beehive type, but differs therefrom in that its base-line. The arched Wall ofthe oven is constructed of s ecially-formed brickthe whole being close by a keystone` of approximate] ovoid form containing a circu ar eye.

'e-brick forming the interior of the oven is backed by a masonry wall fitting closely against the fire-brick, andv said masonry'rwall is backed up-and reinforced by iilling in dirt, shale, and the like. In this manner the bricks are prevented from workin coke-ovens.

Th invention will be hereinafter fully set yndA .particularly pointed out in the claims, I" i In the accompanying drawings, Figure 1 is ourinvention, the same being illustrated in Fig. 2 1s a front elevation. Fig. 3 is a transverse sec- Referring to the drawings, 10 designates' wail of .a battery of coke-ovens A11, said wal being dprovided with lclosed by a fire-brick 15,

s aced-apart openings 12, acentv which the doors of the ovens are located. Each 6,) which is also provided with a threefold ta-v per and-serves as a key to complete or close the tier, the horizontal 'ta er of this latter brick being greater than t e corresponding inner Wall of re-brick 13,

taper of brick 13. The top of the arch is (see Fig. 4,) approximately ovoid'in forni and provided with an eye or o eni 16 to form an outlet'for the pro ucts o com ustion, as is usual in ovens ofl this t e. The brick 15 is the chief keystone of t e arch and affords great stability to the arch and in a great measure the Weight of the latter.- A

The interior wall of the oven is surrounded by masonrybacking 17, closely fitting against the fire-,brick and built in with cement or mortar to make a solid wall. This maso backing is in turn reinforced by a llin of dirt or shale, as indicated at 18. The oor supports i9 of the oven is slightly inclined from the #rear to the front and is composed of ordinary fire-brick tiling of any preferred form. Said door is built upon a solid foundation 20, especiall prepared to y resist Weight and force. -Eac oven in a battery or series communicates with the next adjacent ovens by means of a bore or passage -way 21, whereby the gases and fumes in any one oven are always united by the iiames in the adjoining ovens.

Adjacent the opening 12 of each oven the wall is concaved or arched .horizontally at 22 with the ront ofthe arch toward the interior .of the oven, said arch being formed of tire- 'brick 4The door of the oven vconsists of a metal frame 23, provided with hook-like ro. jections 24, which are built into the wa l to insure greater stability and the retention of the frame in position.

In operation the method of making coke in vour improved ovenis identical with the method followed in the operation ofthe Wellknown beehive ty e. It will be noted, however, that by arcliing` the door of the oven horizontally toward the interior of the oven "will be observed'tliat the front of the oven is the only-place that is not tied into the arches et the oven onI the interior because of the necessity ofleaving a lar e aperture for the r-door, and the object of t e front or horizon tal arch is tosupport thsweakest portion of the interior formation. Another advantage of our improved coke-oven lies in the a proximate y ovoid form thereof, wherebyT t e oven possesses maximum strength and dura-A bility to withstand the intense heat as Well as the strain of as ex lesions during the maximi facture of coke. y constructing the inner wallet fire-brick brought closely together the interior surface of the oven is burned into one homogeneous surface which is almost glass in its simmthness and capable of withstand? the most intense heat or explosions.
